• Large, user-friendly touch screen display
• Life.net remote monitoring provides real-time monitoring of more than 150 operating parameters, immediate identification of problems, and detailed reporting

• High energy efficiency in normal mode and Intelligent Eco-Mode™ operation
• Softscale™ modularity allows capacity growth without increasing footprint
• Life.net remote monitoring and reporting ensures UPS health
• ENERGY STAR^® qualified
• Liebert Services local support and 24x7 call center

Lowest Total Cost of Ownership

• Provides high efficiency in both double conversion and Intelligent Eco-Mode operation – up to 98% efficiency.
• Active IGBT Rectifier reduces size requirements for generator sets, circuit protection, cabling and transformers, minimizing installation and operation costs.
• Optimizes battery life with temperature-compensated battery charging in both double conversion and Intelligent Eco-Mode.
• Supports a full range of leading and lagging power factor loads without derating. Unity input and output power factor ratings deliver more real power for your money.

Higher Availability

• True on-line, double conversion technology corrects for all types of power fluctuations.
• Provides the highest output power quality, with advanced inverter control technology.
• Optional dual bus synchronization of multiple UPS units when feeding independent distribution paths. Continuous-duty static switch standard - enables Ecomode operation,

Flexibility

• Softscale technology conserves capital while providing an economical expansion path with minimal disruption.
• Simple 1+N paralleling provides low initial cost and additional levels of redundancy.
• Parallel up to 6 systems for capacity or redundancy.
• High power density and small footprint deliver more kilowatts per square foot for efficient space utilization.
• Automatically adapts to dynamically changing load power factors (leading and lagging) without derating, modification or recalibration.and is more robust and reliable than a momentary static switch design. Higher overload capacity results in more robust operation.
